Turning Vapour
Into Value
A new era of sustainable, thermally powered solutions for water recovery and industrial heat utilisation.
Engineering Thermal Solutions
Founded in 2005 through a technical collaboration between Italy's SWS and India's GB Engineering, Vapour Desal Technologies has grown into a specialist provider of thermal desalination, advanced vapour systems, and waste-to-energy engineering.
From vacuum vapour systems to low-temperature distillation projects for nuclear facilities and island deployments, our core strength lies in solving complex water and heat-recovery challenges through engineering depth, cost efficiency, and sustainable system design.
Our systems are developed with a strong focus on integration — aligning with available heat sources, site conditions, and operational constraints. This approach enables reliable performance across a wide range of applications, from industrial process environments to remote and infrastructure-critical installations where consistency and durability are essential.
Our Solutions at a Glance
Thermal Desalination Systems
Heat-driven water recovery engineered for industrial reliability, using steam, solar, nuclear, and waste-heat sources. Our systems combine multi-effect distillation, low-pressure evaporation, and heat recovery to deliver dependable freshwater production.
Waste to Energy Systems
Industrial waste streams converted into usable resources through engineered pyrolysis and circular process improvements. From ASME/PED-compliant redesigns to ISCC supply chain enablement — supporting emissions compliance, resource recovery, and efficiency.
Engineering Services
Precision engineering that supports every project stage — from custom pressure vessel design and 3D modelling to controlled fabrication, execution, and commissioning — creating industrial systems that perform reliably over the long term.
Engineered for peak performance and industrial reliability.
Every system we deliver an outcome of nearly two decades of engineering experience, real-world project execution, and deep material science knowledge — applied to your specific conditions.
20+ Years Experience
Two decades of thermal desalination expertise applied to every project we deliver.
